Make word routines into word types Instead of having wordref point to core word routines, I made them into word 4 word types. It liberates space into the stable ABI and should make porting to other arches easier. I'm also thinking of combining word type with the namelen field for precious bytes saving, but not now... 2020-06-18 11:41:01 +10:00			`80 System variables 85 Word types`
Refer to stable wordref by direct offset in "hot zone" immediates Previously, it was impossible to cross-compile Collapse OS from a binary-offsetted Collapse OS because stable ABI wordrefs would have a wrongly offsetted address. This solves the problem by replacing those wordrefs by direct, hardcoded stable ABI offset references. 2020-07-05 21:09:11 +10:00			`89 Initialization sequence 91 Stable ABI`
